This study evaluated the anthelmintic potential of the hydro-alcoholic extract of Ailanthus excelsa stem bark. Earthworms (Pheretima posthuma) were used to test three concentrations of the extract: 100mg/5ml, 250mg/5ml, and 500mg/5ml. The time taken for paralysis and death of the earthworms decreased with increasing concentration. The highest concentration of 500mg/5ml caused paralysis in 60 minutes and death in 73 minutes, faster than the standard drug Piperazine citrate. The results suggest that the hydro-alcoholic extract of Ailanthus excelsa stem bark has significant anthelmintic potential in a concentration

ABSTRACT
Main aim of present study is to evaluate anthelmintic potential of hydro - alcoholic extract of Ailanthus excelsa stem
bark. During the study period, concentration (100mg/5ml, 250mg/5ml, 500mg/5ml) of hydro - alcoholic extract were
used for determining the paralysis time and death time of earthworms (Pheretima posthuma). At the concentration
of 500mg/5ml time required for paralysis (60±0.81 min) and death (73±2.44 min) is minimum. The time required for
paralysis and death of earthworms at the concentration of 250 mg/5ml is (229±1.29 min), (249±2.70 min)
respectively and at the concentration of 100 mg/5ml time required for paralysis and death of earthworms was
(499±1.29 min), (539.5±1.30 min).From the study it was observed that at the higher concentration of the extract
time required for causing paralysis (60±0.81 min) and death of earthworms (73±2.44 min) is less in comparison to
the time required for causing paralysis (120.5±1.29 min) and death (148±2.36 min) of earthworms by the standard
drug ( Piperazine citrate).
Keywords: Anthelmintic potential, Ailanthus excelsa, Pheretima posthuma, Piperazine citrate.

INTRODUCTION
Common name of Ailanthus excelsa (Simaroubiaceae) is mahanimb. Ailanthus excelsa tree is originally from
China. It is also called as ‘tree of heaven’ due to its many benefits for human beings. Traditionally it is used for
curing diseases. Bark of the plant Ailanthus excelsa is used as astringent, appetizer, anthelmintic, febrifuge. To cure
dysentery, skin disease, troubles of the rectum, gout, rheumatism, dyspepsia, bronchitis and asthma stem bark of the
plant is beneficial. It is used to obtain pleasent taste of mouth. As mentioned in traditional medicine, Ailanthus
excelsa is used for curing wounds and skin eruptions. The plant contain flavonoids, quassinoides, alkaloids,
terpenoids, sterols and saponins. Different chemical compounds are present in Ailanthus excels in a large amount
which show potential biological activities. The vast ethnomedical uses inspired us to investigate the anthelmintic
potentials of Ailanthus excelsa stem bark[1].
A large amount of the world population are infected by helminthic infections. In the developing countries They
cause a large threat to health of public especially in under developed countries and cause dangerous diseases like
anaemia, malnutrition and pneumonia. Tape worm, round worm and flukes are the helminthes which infects the
intestine. These infection mostly affects the population living in endemic areas with major social and economic
consequences. In human beings (“the intestinal round worm parasite”) resembles (anatomically and physiologically)
to Pheretima posthuma(the adult Indian earthworm) this is the main reason for using Pheretima posthuma (the adult
Indian earthworm) as a test worm for anthelmintic screening. Earthworms are used as suitable model for screening
anthelmintic drug also due to their easy availability[2].

MATERIALS AND METHODS
Collection of Plant material
Stem bark of Ailanthus excelsa was collected from Jungle of Munda pandey , Moradabad (Uttar pradesh ) in the
month of feburary 2013 and aunthenticated by the the taxonomist. Specimen is deposited in the IFTM museum
(Specimen No. 97895).
Extraction of Plant material
Maceration method - In this method 200 gm of drug powder (powdered form of stem bark of Ailanthus excelsa)
was macerated with mixture of distilled water and ethanol (1:1) and make it stand for 48 hours. Then with the help
of muslin cloth and whatman filter paper the extract was double filtered and the extract obtained was concentrated
by evaporation on water bath. Finally the concentrated extract obtained was dried and used in powder form .It was
observed that % yield of extract was 3.78%.
Anthelmintic activity
Anthelmintic activity was evaluated for hydro-alcoholic extract of stem bark of Ailanthus excelsa. Pheretima
posthuma (Earthworm obtained at the site of Ram ganga (Kathghar) of nearly equal size (9±1cm) were selected for
present study due to its anatomical and physiological resembelence with roundworm parasite of human being. Four
Earthworm of equal size were placed in each petridish at room temperature. Piprazine citrate (200 mg/ 100ml) was
used as reference standard. Before starting the experiments test solutions and standard drug solution were prepared
freshly.The paralysis time (min)[Mean±SEM] was observed and noted when the earthworms(Pheretima posthuma)
did not move except when they were shaken vigorously. Death time (min)[Mean±SEM] were observed and noted
when earthworms (Pheretima posthuma) did not move even when they were shaken vigorously or kept in hot water
(50 ͦ
c).[3][4]

RESULTS AND DISCUSSION
The result were anlayzed for statistical significance using one way ANOVA followed by Dunnett’s multiple
comparison test. Difference at P<0.05 was considered significant. Hydro- alcoholic extract of Ailanthus excelsa stem
bark (Table 1) showed concentration - dependent anthemintic activity against earthworm. Ailanthus excelsa showed
significant effect (p<0.05) at the tested concentration 500 mg/5ml as determined by the paralysis time and death
time.

CONCLUSION
From the present study, it is finally concluded that the hydro - alcoholic extract of Ailanthus excelsa stem bark
showed significant anthelmintic potential. To isolate phytoconstituents form the hydro- alcoholic extract from the
stem bark of Ailanthus excelsa is under investigation.
